Used primarily as an intermediate in pharmaceutical synthesis, especially in the preparation of biologically active indole derivatives. Its boron-containing group enables cross-coupling reactions, such as Suzuki-Miyaura coupling, allowing the formation of carbon-carbon bonds in drug development. Commonly applied in the synthesis of kinase inhibitors and other therapeutic agents targeting cancer and inflammatory diseases. The compound’s structure supports high reactivity and selectivity in late-stage functionalization of complex molecules, making it valuable in medicinal chemistry research and development.
